Objective 10/8/2012 Describe the theory of plate tectonics. Intro Pick up worksheet from front table. Grades posted on Student Wall Which piece(s) of evidence proved the Theory of Continental Drift?
Theory of Plate Tectonics
Theory of Plate Tectonics Tectonic Plates Large, puzzle piece- like portion of the lithosphere Not all the same shape Can be large or small Can contain both types of crust “float” on asthenosphere
Tectonic Plates A Tectonic Plate close-up…
Theory of Plate Tectonics States that the Earth’s lithosphere is broken into moving plates driven by convection currents in the mantle
Tectonic Plates and Waves Summary: The Lithosphere is broken up into huge pieces called Tectonic Plates. These tectonic plates “float” around on the asthenosphere. The Theory of Plate Tectonics states these plates move by convection currents.
Objective 10/8/2012 Describe the theory of plate tectonics. Outro Compare and contrast the Theory of Continental Drift with the Theory of Plate Tectonics. (Comparing/Contrasting foldable)
